Abstract
Abstract A combination gas receiver-liquid separator unit for use in a liquid injected gas compressor system. The receiver-separator unit comprises an elongated cylindrical vessel having a transverse partition sealingly dividing the vessel into two separate compartments for separating liquid entrained in a flowing gas stream and for storing liquid-free gas under pressure. A check valve interposed between compartments prevents the backflow of liquid-free gas into the separator compartment. The separator compartment includes a primary inertial separation stage and secondary and tertiary impingement type separation stages. The secondary and tertiary separation stages comprise a removable separator element. The separator compartment also serves as a liquid reservoir for the associated gas compressor system.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
238 words
A receiver-separator for a liquid injected gas compressor comprising: an elongated tank defining a closed vessel; partition means disposed in said tank sealingly dividing said tank into two separate compartments; one of said compartments comprising means for receiving a gasliquid mixture under pressure; the other of said compartments comprising means for receiving and storing substantially liquid-free gas under pressure; said one compartment includes gas-liquid inlet means and vent means comprising a conduit opening from the exterior of said tank into said one compartment and valve means interposed in said conduit and operable to be opened to reduce the pressure of said gas-liquid mixture in said one compartment, said one compartment includes liquid separator means for separating liquid entrained in said gas-liquid mixture received therein, and said one compartment includes liquid reservoir means for receiving and storing liquid separated by said liquid separator means; said other compartment includes gas outlet means and means for sensing a predetermined pressure in said other compartment; conduit means opening from said one compartment into said other compartment; control means responsive to said means for sensing a predetermined pressure to open said valve means; and, check valve means disposed in said conduit means between said compartments operable to prevent the flow of a plurality of separation stages gas from said other compartment to said one compartment when said valve means is opened to reduce the pressure of said gas-liquid mixture in said one compartment.
Claim 2
Dependent Claim
238 words
A receiver-separator for a liquid injected gas compressor comprising: an elongated tank defining a closed vessel; partition means disposed in said tank sealingly dividing said tank into two separate compartments; one of said compartments comprising means for receiving a gasliquid mixture under pressure; the other of said compartments comprising means for receiving and storing substantially liquid-free gas under pressure; said one compartment includes gas-liquid inlet means and vent means comprising a conduit opening from the exterior of said tank into said one compartment and valve means interposed in said conduit and operable to be opened to reduce the pressure of said gas-liquid mixture in said one compartment, said one compartment includes liquid separator means for separating liquid entrained in said gas-liquid mixture received therein, and said one compartment includes liquid reservoir means for receiving and storing liquid separated by said liquid separator means; said other compartment includes gas outlet means and means for sensing a predetermined pressure in said other compartment; conduit means opening from said one compartment into said other compartment; control means responsive to said means for sensing a predetermined pressure to open said valve means; and, check valve means disposed in said conduit means between said compartments operable to prevent the flow of a plurality of separation stages gas from said other compartment to said one compartment when said valve means is opened to reduce the pressure of said gas-liquid mixture in said one compartment.
Claim 3
Dependent Claim
53 words
The invention set forth in claim 1 wherein: said liquid separator means includes means forming a plurality of separtion stages for successively receiving a flow stream of a gas-liquid mixture and operating on said mixture to separate liquid therefrom, said plural separation stages including primary inertial separation means and secondary impingement separation means.
Claim 4
Dependent Claim
76 words
The invention set forth in claim 2 wherein: said inertial separation means includes a substantially cylindrical baffle mounted in said one compartment, said cylindrical baffle having an interior area comprising a primary separation chamber, and said gas-liquid inlet means comprises a conduit disposed in said one compartment to discharge said gas-liquid mixture tangentially against the inner wall of said baffle whereby said mixture is forced to flow in a vortiginous manner within said primary sepaRation chamber.
Claim 5
Dependent Claim
49 words
The invention set forth in claim 2 wherein: said impingement separation means comprises a foraminous wall structure defining a hollow cylindrical element interposed in said one compartment in said gas-liquid flow stream between said primary separation chamber and said conduit opening from said one compartment into said other compartment.
Claim 6
Dependent Claim
79 words
The invention set forth in claim 4 wherein: said impingement separation element is disposed in a secondary separation chamber formed within said one compartment, said secondary separation chamber is defined by the interior area of a substantially cylindrical shell extending longitudinally within said one compartment from one end of said tank to a transverse partition intermediate the ends of said shell and said shell includes an opening into said secondary separation chamber in communication with said primary separation chamber.
Claim 7
Dependent Claim
60 words
The invention set forth in claim 5 wherein: said impingement separation means includes tertiary separation means comprising a transverse end wall of said cylindrical element located adjacent said transverse partition intermediate the ends of said shell and interposed between said foraminous wall structure defining said hollow cylindrical element and said conduit opening from said one compartment into said other compartment.
Claim 8
Dependent Claim
56 words
The invention set forth in claim 6 together with: tertiary chamber means formed between said transverse partition intermediate the ends of said shell and a transverse partition adjacent the end of said shell opposite said one end of said tank, and said tertiary chamber means is operable to receive liquid separated by said tertiary separation means.
Claim 9
Dependent Claim
28 words
The invention set forth in claim 7 together with: conduit means in communication with all of said separation chambers operable to drain said chambers, individually, of separated liquid.
